基于DSP的基带成型滤波器设计

The Design of Baseband Shaped Filter Based On DSP

在无线通信中,基带脉冲成型滤波器是全数字调制器的核心模块之一。探讨基带成型滤波器原理,使用Matlab软件设计了基带成型滤波器的系数,以TMS320VC5409芯片为核心进行设计。在CCS环境下进行仿真,结果表明:所设计的基带成型滤波器计算量小,实时性好,系数可以在系统中方便地修改,符合数字通信软件化的趋势。

In wireless communications, baseband pulse shaped filter is digital modulator is one of the core module. The principle of baseband shaping filter, designed using the iatlab software baseband shaping filter coefficients to TMS320VC5409 chip as the core design. In the CCS environment simulation, results show that the design of the base-band shaping filter small amount of calculation, real time, the coefficients can be easily modified in the system, in line with the trend of digital communications software.
